\( Z_C = -j \; X_C \)
where \( j \) is the imaginary unit and \( X_C = \dfrac{1}{ \omega C } \) is the capacitive reactance in Ohms \( ( \Omega ) \)
In polar form , \( Z_C \) is writtean as
\( Z_C = X_C \; \angle \; - 90^{\circ} \) or \( Z_C = X_C \; \angle \; - \dfrac{\pi}{2} \)
\( \omega = 2 \pi f \) is the angular frequency in radians per second (rad/s) and \( f \) is the frequency in Hertz (Hz).
This calculator calculates angular frequency \( \omega \), the capacitive reactance \( X_C \) and the impedance \( Z_C \) in complex standard and polar forms.
